FINGER-BAR AND FINGER FOR MOWlNG-MACHINES.

fiPECIFICATION forming part of Letters Patent No. 332,671, datedDecember 15, 1885.

Application filed July 15, 1884. ScrialNo. 137,740. (No model.)

To all whom it may concern.-

Be it known that I, DEWITT (J. MARI;- HAM, a citizen of the UnitedStates, residing at Towanda, in the county of Bradford and State ofPennsylvania, have invented certain new and useful ImprovementsinFinger-Bars and Fingers for Mowing-Machines; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My present invention relates to the attachment of the finger-bar of amowing-machine to the shoes and to the knife-keepers for retaining theknives in position. The method of the attachment of the finger-bar tothe shoes is especially applicable to front-draft mowingmachines,similar to that described in Letters Patent No. 304,837, granted to meSeptember 9, 1884; but the knife-keepers are adapted to any kind ofmachine or finger-bar.

In the accompanying drawings, which illustrate my invention and formpart of this specification, Figure 1 is a plan view of a por-- tion ofthe finger-bar of a mowing-machine. the knife being removed. Fig. 2 isavertical section in a plane indicated by the line 2 2, Fig. 1, showingthe attachment of the fingerbar to the shoe. Fig. 3 is a verticalsection in a plane indicated by the line 3 3, Fig. 1, showing thelocation of the knife-keeper, in this view the knife being shown. Fig. 4is a front view of the knife-keeper detached, and Fig. 5 is a bottomview of the knife-keeper.

Like letters designate corresponding parts in all of the figures.

The finger-bar A is beveled downwardly on its forward side, as shown ata, and the shoe B is made with an overlapping part, b, which exactlyfits over the beveled edge a, when the finger bar is in place. Thefinger bar is further fastened to the shoe by a bolt, 0, passing throughthe finger-bar and shoe, which is secured by a nut, d. Secured to thefinger-bar at proper intervals are the usual guards, O 0, provided withguardplates 6. These guards are also formed with overlapping portions f,which exactly fit over the beveled edge a of the cutter-bar, and are bythis means more securely held in position. The knife D is formed with aknife-head, E, above, and with a bottom plate, F, which is set forwardof the rear edge of the knife, as shown, so as to form abearing-surface, g, along the knife. This bearing-surface grests upon aledge, it, formed in the guards O O, and the bottom plate, F, also restsupon a ledge, t, formed in the guards, these ledges,

h 'i constituting the bed or channel along which the knife slides. Theshoe B, as well as the guards, is formed with similar ledges,

h t. The knife-head Eis beveled on its upper front edge, as shown at j.The knifekeepers G G are secured by bolts at suitable intervals to thefinger-bar. Each knife-keeper is formed with side wings or flanges, H H,extending alongside the knife-ehannel,provided with bolt-holes k k, bymeans of which it is secured to the finger-bar, and with an upwardly andforwardly extending projection, I, located centrally between saidflanges, which, when the knifekeeper is in position passes closely overthe knife-head, and prevents any vertical movement of the knife. Eachknife-keeper is secured in such position so that the vertical side Z ofthe projection I forms a back guide for the knife-head E.

To insure the proper and exact position of the knife-keeper, it isformed on its under side with grooves m m, which fit over projec- 8otions it a, formed either on the finger-bar or on the overlapping partfof the guards O C. The projection I of the keeper is formed with alip,J, which extends downward over the beveled edgej of the knife-head, inorder to prevent any forward movement of the knife. The knife is thusheld by the keeper with its projection I and lip J by the flanges H H,and by the ledges formed in the guards, and these parts form the guidesbetween which 0 the knife reciprocates easily and exactly.

I claim as my invention 1. The finger-bar of a mowing-machine formedwith adownwardly-beveled front side,

a, in combination with the shoes of a mowing-machine, upon which theends of said finger-bar rest and to which said bar is secured, saidshoes being formed in front of said bar with an upwardly-extending over-In testimony whereof I affix my signature in IO lapping part, b,.whichfits over the beveled side presence of two witnesses. of the finger-bar,substantially as set forth.
